Well we have answers now :)
It is soft tissue :( However it is NOT in the shoulder thank goodness (a pain in the rear to treat and keep rested)...but rather behind the shoulder. And there are other issues associated with compensation (aka taking weight off those muscles).
During her massage today, she was having severe muscle spasms in her left triceps, spinalis dorsi, latissimus Dorsi and semitendonosis. She also had tightness in her right satorius and left cleidocervial muscles. AKA a whole lotta spasms going on :-((
She was great for the massage, but as soon as the therapist got near that area behind the shoulder she wanted OFF the table...poor kiddo :(
So she is on leash walking, for another 2 weeks, icing everyday on the area and a recheck in 2 weeks. I am VERY grateful she can go on leash walks! The poor dog doesn't do well on crate rest!!!!! She will probably be on leash walking for 4-6 weeks :(
COULD be worse!!!!
Thank you to everyone for keeping up on this :) I appreciate all the healing thoughts!!!!
